The report comes as the prescience of the likes of Charles Kennedy and Jeremy Corbyn - then Liberal Democrat and Stop the War leaders, respectively - has received not undue praise, while the war-mongering attitude of The Sun, among others, has been heavily criticised.

Over the course of the last thirteen years, public perception has gradually flowed against the war - it peaked in April 2007, two months before Tony Blair resigned as Prime Minister.

Three in five people were then opposed to the war, but this dropped five per cent in the weeks after Gordon Brown replaced Blair as Prime Minister.

Immediately before the Chilcot Report was released, just one in four people thought Britain was right to go to war, compared to a big majority - two in three - back in April 2003.

According to the poll, Labour supporters were least likely to think war was the right decision at the time, despite it being a policy of a Labour government.
